Special Notes
  • DisplayPort™ 1.4 is required on graphics card and video source to achieve 8K @ 30
  • DisplayPort™ 1.4 and Display Stream Compression (DSC) is required on graphics card and video source to achieve 8K @ 60
  • A 4K-capable display and cable is required for obtaining the 3840 x 2160 resolution
  • If connected to a USB™ 2.0 host port, or if using a USB™ 2.0 host cable, performance may be limited
  • The adapter can connect to a USB-C® port that doesn’t support Power Delivery, but it will not pass power through the connected device
  • If you are using high-powered USB™ devices, attach a USB-C® power adapter to the power delivery port to ensure maximum performance. To avoid disruption, do not remove the power adapter while copying files.
  • We advise no more than one (1) bus-powered/portable external hard disk drive to be connected to the adapter at a time
